Abstract
The invention discloses a fertilizer synergist special for paddy and application thereof. Each 1000kg of chemical waste residue phosphorus gypsum includes 3-6kg of potassium citrate and 2-4kg of humic acid or potassium humate. About the last week of planting paddy, the synergist product is uniformly scattered into the field according to 100-260kg per mu and is plowed into the soil to be uniformly mixed with the soil. When the paddy rice seedling is transplanted, 25-40kg of 32% 12-10-10 compound fertilizer is applied and 10-20kg of urea is applied when the paddy is jointing. The product can activate the insoluble nutrients of the soil, can improve the utilization ratio of the fertilizer by over 25 percent, save more than 30 percent of the chemical fertilizers and can increase production by 10-25 percent, and has obvious economic and environmental ecological benefit.
Description
Technical field
The invention belongs to environmental protection technology and agricultural technology field, be specifically related to fertilizer synergist for special paddy and application thereof that a kind of recycling of solid chemical industry waste prepares.
Background technology
Phosphogypsum is the solid waste of Phosphate Fertilizer Industry and phosphoric acid industry, at will throws aside environment, often contaminate environment, also cause the waste of resource, annual ten thousand tons of the phosphogypsum waste 3000-5000 that produce of China as unreasonable disposal and utilization, will produce serious environmental problem.
Paddy rice is China's staple food crop, and rice is China resident tradition staple food.Long-term a large amount of chemical fertilizer that use continuously cause chemical fertilizer utilization ratio to reduce, increasing environmental pollution, and rice yield descends, and quality reduces, and the economic benefit of rice cultivation descends.
Compound manure is a kind of relatively formula fertilizer of science, but effect is different on different areas, different soils, Different Crop, be mainly because single shoot proliferation can not satisfy the growth needs of various crops simultaneously, thereby reduced the utilization ratio of composite fertilizer.
Utilize the synergistic agent of phosphogypsum production not only to solve the problem of phosphogypsum contaminate environment, solved simultaneously the problem of compound fertilizer dedicated to paddy utilization ratio, improved the utilization ratio of chemical fertilizer.
Summary of the invention
Goal of the invention:The object of the invention is to provide a kind of fertilizer synergist for special paddy and application thereof, solves phosphogypsum pollution and the not high problem of paddy rice use chemical fertilizer utilization ratio in the phosphorous chemical industry process, the usage quantity of saving chemical fertilizer, simultaneously free from environmental pollution again, ensure food safety, improve output, increase farmers' income.
Technical scheme:Fertilizer synergist for special paddy, contain in every 1000kg chemical sludge phosphogypsum:
The 3-6kg Tripotassium Citrate, and
2-4kg humic acids or potassium humate.
The application of above-mentioned synergistic agent in Rice Cropping, rice cultivation evenly apply the field with this synergistic agent product by every mu of 100-260kg about the last week, and plough under in earth and native mixing, during the transplanting rice rice shoot, use 32%(12-10-10, N, P
2O
5, K
2O total nutrient content is 32%wt, and wherein N content is 12%wt, P
2O
5Content is 10%wt, K
2O content is 10%) composite fertilizer 25-40kg, use again urea 10-20kg during the paddy rice jointing.
Beneficial effect:The phosphogypsum that uses in the present invention is to produce the solid waste that produces in phosphoric acid and phosphate fertilizer process, and contaminate environment benefits the society, and is a kind of public welfare environmental protection technology.
Contain a large amount of calcium sulfate, calcium phosphate, secondary calcium phosphate etc. in the phosphogypsum that adds in the present invention, also contain the trace elements such as magnesium, boron, zinc, nickel, silicon, copper, particularly silicon, be indispensable necessary element in growth process of riceplant, strengthens lodging resistance and the disease resistance of Culm of Rice; Sulphur, phosphorus, calcium are all the nutritive elements that plant growth needs, and promote crop leaf photosynthesis; The Determination of multiple metal elements that contains in the chelating such as Tripotassium Citrate and humic acids or complexing phosphogypsum makes it become the complex compound that can slowly discharge nutrient.Contain in addition a large amount of calcium ions in this synergistic agent, can effectively improve saline-alkali soil and Middle and low productive paddy soils earth colloidal property, increase soil aggregate, improve the production performance of soil.
The nutrient of product energy activating soil indissoluble of the present invention can improve utilization rate of fertilizer more than 25%.Save the fertilizer application amount more than 30%, can make increasing production of rice 10-25%, have significant economy and environment ecological benefits.
The following beneficial effect that the present invention has compared to existing technology:
1) the present invention can effectively solve the environmental pollution of a large amount of solid waste phosphogypsums that discharge in the phosphorous chemical industry process, and the change refuse is resource, contains the elements such as the required silicon of a large amount of paddy growths, calcium, sulphur, phosphorus for the crop growth.
2) the present invention with the regeneration of chemical industry changing rejected material to useful resource, meets the requirement of energy-saving and emission-reduction.
3) compounding application together with paddy rice composite fertilizer of the synergistic agent in the present invention, can improve utilization rate of fertilizer.
4) the various trace elements silicon that contains in the present invention, magnesium, manganese, zinc, sulphur, boron, molybdenum etc. can provide the use of paddy growth, also can be supplied with beneficial microorganism and use, and can improve soil microenvironment.
